DESCRIPTION

Specifically designed to fit under the stock or aftermarket primary/derby covers and increase the capacity of your stock clutch by using stainless steel weighted arms that progressively increase pressure to the clutch as rpms increase
This also allows lever effort to be kept to a minimumeven with big-inch motors
Three different sets of six coil springs (light, medium, heavy) are included for a variety of spring pressure options
Coil spring design provides much smoother shifting and a more progressive, linear engagement compared to a diaphragm-type spring
Simple bolt-on installation is all that is required with no modifications needed
Cable-actuated and hydraulic versions are available
Made in the USA

While universal products are designed to fit a range of vehicles they may not fit all vehicles. If you are unsure of the fit we recommend posting a question on the ThumperTalk forums or contacting the manufacturer before ordering.
